Your motorcycle is equipped
with Digital Motor Electronic
(MOTRONIC) engine manage-
ment and a high-output ignition
system.
d Warning:
When the engine is running or
the ignition is switched on, do
not touch electrically live
components, terminals or
wiring.
–Risk of fatal accident!
Work on the electrical system
only when the circuit has
been interrupted (switch off
ignition). For greater safety,
disconnect and insulate the
negative battery lead. If you intend to perform the
maintenance and general care
work described in the following
section yourself, you must pos-
sess the necessary knowledge
of technical matters and
mechanical skills.
Your motorcycle is built to high
technological standards. Spe-
cial tools and purpose-
designed diagnosis and testing
equipment, together with the
appropriate knowledge, are
needed to keep your motorcy-
cle in optimum working order.
